HR Series Replaceable Valve Seat Thermodynamic Steam Traps

Horizontal installation, maximum pressure difference 260bar, maximum displacement up to 760Kg/h

 

Features

Online replaceable valve seat module for easy maintenance.

Highly precision ground discs ensure a tight seal.

The heat shield reduces heat radiation losses and increases the cycle time under no-load conditions, extending the service life.

Can withstand overheating, water hammer, freezing, and corrosive condensation.

The “click” sound when the disc falls into the valve seat makes it easy to check the working performance.

With built-in large filter area to ensure trouble-free operation.
